An 18-year-old man was found with stab wounds near Dagenham Heathway station at 11.47pm on Friday (May 5).

Metropolitan Police officers and the London Ambulance Service attended the scene, but despite their best efforts he sadly died.

A 20-year-old man has been arrested on suspicion of murder and remains in police custody.

A police spokesperson said that the victim’s family have been made aware and a post-mortem is to be schedule in “due course”.

A second man was taken to hospital with a stab injury following the incident. His condition is not believed to be life-threatening.

A number of crime scenes remain in place.

Detective Chief Inspector James Shirley said yesterday (May 6): "My thoughts are with the young man’s family and friends.

“I want to offer my full reassurances to them, and the wider community, that despite the significant events taking place in London today, the focus of my team is bringing the person or people responsible to justice.

“Our investigation is progressing at pace and I would thank everyone who has already spoken to officers. I would ask anyone who has not yet come forward to do so as a matter of urgency.

“I would also ask local residents to check dash cams and doorbell footage for anything out of the ordinary and share that with us as soon as possible.”

Anyone with information is urged to contact police on 101 or tweet @MetCC quoting 8711/06May.
